Abstract
The present invention discloses a soluble polythiophene derivative containing highly coplanar repeating units. The coplanar characteristic of the TPT (thiophene-phenylene-thiophene) units improves the degree of intramolecular conjugation and intermolecular π-π interaction. The polythiophene derivative exhibits good carrier mobility and is suitable for use in optoelectronic devices such as organic thin film transistors (OTFTs), organic light-emitting diodes (OLEDs), and organic solar cells (OSCs).
